Application February 12, 1947, Serial No. 728,011

2 Claims.

My invention relates to an improvement in sewing machines provided with horizontal feeding disks or cups, and consists of a work piece guide on such machines, which is very rigid although adjustable in all directions, up and down, sideways as well as in and out. This guide is shaped and bent so as to give ample room for the operators fingers.

These and other objects and advantages are made clear in the subjoined description with the aid of the attached drawing.

Like numerals denote the same details in the different views.

In the drawing:

Figure 1 is a fragmentary front elevation of a cup feed stitching machine with my attachment for guiding the work piece;

Figure 2 is a side elevation as seen left side of Figure 1;

Figure 3 is a top plan view of Figure 1;

Figure 4 is a side elevation and partial section as seen from the right side of Figure 1;

Figure 5 is a front elevation of the guide foot for the work piece.

One embodiment of the invention is here shown and reference numeral l0 denotes a sewing machine for leather goods of a conventional type.

The sewing machine [0 is provided with the usual horizontally reciprocating needle H. To the left of the needle is attached on the front side of this machine l0 a guide 12. This guide forms the main feature of this invention, set in convenient position for free movement of the operators left hand and quite close to the feeding device to allow plenty of room to work. This guide I2 is therefore furnished with the terminal fiat foot M which is horizontal in a plane relatively close to the plane of the tops of the feeding disks [3 and I6 across which reciprocates the needle I I carried by the reciprocating holder from the The guide l2 consists of a relatively long arm H of round cross section which extends straight out from the machine. The outer end of the arm l2 joins a substantially right angularly disposed portion i2" which lies in a vertical plane passing between the discs l3 and I6 and extends at a downward inclination terminating in the fiat foot M. The arm I2 is slightly flattened at the inner end I! for engagement by set screws la in the socket 19 of a bracket 20 which is held on by 2 clamp screws 2| with large washers 2la. This bracket is adjustable up and down, as well as sideways on the machine by providing screw holes at larger diameter than that of the clamp screws These clamp screws 2| and set screws 18 must be drawn up tightly in order to position the flat foot I4 firmly, after being adjusted both in and out, up and down, as well as sideways above the surface of the disks l3 and IS, in order that the operator may be able to accurately position the work with its fold 29 against said foot 14 to determine the depth of the stitches in the material to be sewn.

The numeral 25 designates a needle guide plate which is securedon top of the disk It as shown. This plate has the usual needle guide groove [8 in which the needle I l reciprocates.

The folded leather or work piece 28, Figures 2 and 4, is held between the knurled peripheral edges of the disks l3 and I6, and abuts with its fold 29 against the foot l4, while the free edge 30 of the work piece extends above the same.

In this manner the double folded leather piece 28 will be stitched in the usual manner, in machines of this kind, with a double-thread chain type, over stitched, the threads passing thru the fold 29 and over the edge 30.

It is to be understood that the invention as herein disclosed may be varied from the details described and shown without departure from the spirit of the subjoined claims.

I claim:

1. In a sewing machine adapted to overseam a fold and an adjacent free edge of a piece of material, including a pair of horizontal feed wheels, a horizontally disposed needle, and a horizontally disposed needle guide, a work guide comprising an angled arm having one of its ends adapted to be supported from the frame of themachine above and to one side of said feed wheels, and a flattened foot element formed at the other end of said arm and disposed above and with one edge thereof disposed outwardly of the free end of said needle guide, whereby the fold of the material to be sewn is guided along the under side of said foot element and the adjacent end of the needle guide with the free edge of the material disposed along the side of the foot element opposite from the said end of the needle guide.

2. The invention as defined in claim 1, with the said work guide arm comprising a length of metal rod bent intermediate its ends to provide substantially right angled portions, one of said portions having its free end flattened for its securement in a supporting socket mounted on the frame of the machine, and the other portion havin its free end angularly bent and flattened to provide the said foot element, said foot element being horizontally disposed relatively to the top side of the said needle guide.
